Well I'd like to start of saying, I'm sick of seeing so many 3, and 4 colered decks! I mean they don't work! I made one once and lost every time I played! Well, I have seen some good three colered decks, but going up any higher is useless! The major problems in multi decks is that you can't put in as many trainers, and basics! I've seen decks that just have only 7 basic pokemon! In DCI tournaments You have to have at least 6 basic pokemon. Say your six prizes were all but one of your basics? Guess what that makes you, a LOSER! And those trainers become major life-savers! Without em' your good as dead! If you really, I mean really, want a multi deck go with Tyler's idea. No fire, IT SUCKS! Oh believe me, I become six cards richer every time I play those kids. Electric, good in that you have Electabuzz and Raichu, and spare that ZAPDOS! HE EATS UP YOUR ENERGY! But, if you want to go deaper on that subject go to quick picks at tyler's part. In the end, They could be both depending on the types you put in or the pkmn you put in.
